Quadro P4000 with SLI Mosaic

Hi, I have two Quadro P4000 cards in a system running Manjaro Linux with driver in version 418.43. The configuration already works with Base Mosaic, now I want to enable SLI Mosaic using a SLI HB bridge.

I followed the instructions as described by http://download.nvidia.com/XFree86/Linux-x86/340.104/README/sli.html.

After executing nvidia-xconfig --sli=Mosaic and restarting the display manager, the desktop starts and the display flickers a few times. The nvidia-settings tool doesn’t show the SLI Mosaic Mode Settings entry.

After searching the Xorg.0.log I found the following errors and warnings:

[   422.353] (**) NVIDIA(0): NVIDIA SLI Mosaic mode selected.

According to the Xorg log, both cards are on a 16X PCI Express slot.
